I absolutely love these!  We live on the side of a mountain, so our backyard has hills and valleys, and not a lot of flat space.  We got two of these and were able to set them up side by side on the spot we had available.  The material is thick and feels like it will last.  They are sturdy, with heavy zippers on the doors.  They were easy to assemble, once I figured out that the frames went INSIDE, and once I recruited help.  I am 63 years old, 5'5" and 145 lbs, and I could NOT manage to hold the tent up while getting the frame where it needed to be.  Now that they are up, I can bring all of my seasonal decorations and camping gear home from the storage unit.  I am a happy camper for sure!
